EXPERIENCE OF CONSTRUCTION OF THE PLATE AND PILE FOUNDATION IN COMPLEX ENGINEERING AND GEOLOGICAL CONDITIONS

Abstract

Purpose. An urgent issue for the construction of foundations in complex engineering and geological conditions is the development of new technologies for the construction and monitoring of buildings built in deep beams. The purpose of this article is to development a technology for eliminating cavities with the help of vertical rigid soil-cement elements. Methodology. Using the experience gained in designing foundations in complex engineering and geological conditions, it was proposed to implement a new type of pile-slab foundation. It includes reinforced vertical hanging piles based on drilling and mixing technology and a slab foundation. An algorithm for monitoring houses built in deep gorges and pile-slab foundations using a system of wells and marks is also proposed. Findings. Scientific substantiation of construction technology in Solomianskyi District of Kyiv has been performed, where there are areas that, given the variable height and saturation of various wastes, are very difficult to use for construction, especially in the construction of houses with large area and height within 9 … 16 floors. The results of construction of a ten-storey frame-type residential building with an underground length of 102.5 m and a width of 14.0 m are presented. Originality. Based on the performed calculations, the dependences of the deformed state of the pile-slab foundations during the construction of high-rise residential buildings are obtained. It is proved that when applying the technology of creating vertical hanging piles, the values of maximum allowable deformations of the house and the foundation meet the requirements of current regulations of Ukraine. Practical value. The use of pile-slab foundation in complex engineering and geological conditions made it possible to develop the technology of construction of a ten-storey building.
